Be it known that I, Jesse C. THorrPsoN, a citizen oft-he United States, residing" at Westfield, in the county of Hampden and State of Massachusetts, have invented new and'useful Improvements in Vapor-Burners,

' of which the following is a specification.

The invention has for its general object a portable lamp or illuminating device adapted for burning carbureted air.

Other objects will appearand be better understood from the following description taken in connection .with the accompanying drawings, in which, I

Figure l is a View of the device partly-an elevation and partly in vertical section. Fig. 2 is a detail vertical seet-ion of the generator and head taken approximately on the line 2-2 .ofFi 1. Fig. 3 is a detail sect on and plan on the line 3-3 of Fig. 2. Fig. 4 is a detail perspective of the. parts of the air conduit or tube. Fig. 5 is a detail plan partly in section of the shade support. Fig. 6 is a detail end view of one of the mantle tubes. be

5 indicates the reservoir which may of any suitable contour and adapted to contain the illuminating fluid 6 and preferably formed with an enlarged base 7 so as to' support the device as a whole when placed upright on a table or the like.

8 indicates a tube extending upwardly from the bottom of the reservoir and through the top 9 thereof and communicating with the reservoir through i openings 10' arranged adjacent to the lower end of the tube. The tube extends upwardly beyond the reservoir for any suitable distance and the 1o1ntbetween the tube and top 9 of-the reservoir is air-ti ht.

10 in icates an outer casing or ornament surrounding the "tube and 11 a valve for controlling the passage of fluid through the tube and operable from the exterior of the casing or ornament 10. r

12 indicates a check valve arranged in the top 9 of the reservoir and adapted for connection to an air pump or other device suitable for charging the reservoir with a quantity of compressed air which serves to force the liquid upwardly through the tube through the openings 10 thereof. The upper part of the tubeconstitutes a generator and car-' a priming cup 13.

' 14 indicates an inner tube suitably secured in the generator and 15 an asbestos wiclg whichv extends through the generator and checks the too free flow ofliquid there, through,"whereby,-to insure of proper vapor izationfi" v H 4 16 indicates a choked passage at the upper end of thegenerator, this passage being formed-by either contracting the upper end ofthegehratbror' in any other suitable manner-such as by forming a tapered open- I ingin the reduced-portioxf 17 of a nozzle having an enlarged portion 18 adapted to screw-onto the upper end'of the-generator. a indicates the burner head. herein shown,

comprising acasing interiorlylformed to pro- 1 vijde-a 'serie's-of'relatively spaced tubes of equal length and consisting-of a central mixing charhberlQ'ztdapted for detachable connection totlfe upperend of the generator .and gas pass g s 20. The mixing chamber 1 communicates with the gas passages, while thelower ends ofithegaspassages 20 are adapted to provide. mantle supports for the asbestos mantles 21.

Z) designates the air tube or conduit 2 through which the air passes into the mixing chamber 19. .By' preference this element is arranged so as to permit of access to the choked passage l6should the latter become clogged with extraneous matter contained in 2 the fluid 6;- A convenient construction for eflecting this result consistsin forming the conduit with an-elbow 22 having a rib 23 to pivotally connect to a lug 24011 the exterior of the mixing chamber 19. The elbow 22 is angular sothatwhen one side thereof depends the end portion of the opposite side will form a continuation of the lateral opening 25 in the mixing chamber 19.

26 and 27 indicate the sections of the air 9 tube or conduit, the latter of which connects with the elbow 22 and the former of which is adjustably secured-to the section 27- and has openings 28 adapted toalinewith openings 29 of the'section 27 when turned into 1 one position,-the said section 26 being further adapted to seal or partially seal the openings 29 when turned to other positions, whereby, to regulate the quantity of air passing into the mixing chamber. 1

The shade support 0 is expansible so as to conform to the diflerent sizes of shades. In this connection it will be observed that the said supportincludes astationary part d made up'of a plurality of radial arms '30 1 connected at their inner ends by-a pierced head 31.

of the cam slots will force the sections 32 outwardly, whereby, to expand theshade holder. The disk 31- has a central opening adapted to receive the shank 37 of a screw which passes through the portion (Z and screws into the upper end of the burner head a. Each section of the shade support has a lateral flange 38 which forms a bearing surface for the ordinary shade.

In use, a quantity of fluid such as gasolene is introduced into the reservoir 5 the check .valve 12 having first been removed there-- from. By preference the quantity of oil or gasolene will not be sutlicient to completely fill the chamber as shown in Fig. 1. This done, the valve 12 is connected to the reservoir after which air is compressed into the latter as before stated. hen .it is desired to use the device a quantity of fluid is introduced into the primary 13 and ignited so as to heat the generator. This done, the valve 11 is opened, whereupon the fluid will be forced upwardly and into the generator where it will be vaporized by the heat of said generator. The air tube or conduit having been regulated, the air passing therethrough will mix with the oil vapor in the' mixing chamber 19. The mixture will thenflow through the chambers 20 whereupon it since various changes will be made, ithin the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

- What I claim asnev'v is:

In a vapor burner, the combination with a generator, of a burner headdetachably connected' to the generator, said burner, head com risin a casin interiorlv formed to provide a central mixing chamber having a' lateral opening adjacent its point of connection with the generator and gas passages disposed onoppositesides of said mixing chamher in depending spaced parallel relation thereto, and communicating therewith, a lug .formed on the exterior of said mixing chant ber directly above the lateral opening, an air conduit consisting of an elbow pivota-lly connected to the lug and disposing the former in registration with the lateral opening.

In testimony whereof I afiix my signature in presence of two witnesses.
